Auxiliary clamping operation device for spray can

ABSTRACT

An auxiliary clamping operation device detachably securable to a spray can is disclosed to include a grip. The grip includes two clamping parts disposed at one end thereof, and a receiving space defined between the two clamping parts. Each clamping part has a triggering portion and a positioning portion disposed on opposite sides. The two trigger portions are fastened together so that the two positioning portions are drivable by the trigger portions to move between an open position where the spray can is separable from the clamping parts, and a close position where the clamping parts clamp the spray can.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to spray cans and more particularly, to anauxiliary clamping operation device for spray can.

2. Description of the Related Art

A spray can generally comprises a pressure can and a valve located onthe top side of the pressure can. When the valve is opened, the contentsof the pressure can are released in a mist. Therefore, it is suitablefor all kinds of medical and health products, cosmetics, householdcleaning and maintenance products and industrial supplies. The valve isusually equipped with a button that can be pressed by the user. Thebutton may be slightly leaked after a long use, and the user maydirectly contact the contents ejected from the pressure can during thepressing of the button, causing inconvenience in use, and even affectingthe health of the body.

At present, there is a sprayer for assisting the holding of a spray can.The sprayer can be directly assembled in a spray can, so that the usercan hold and operate the spray can, preventing dropping of the spray canor user contamination by the contents of the spray can.

However, the operation of the existing sprayer for spray can is stillrelatively laborious, and there are many components, and the assemblyprocedure is complicated, resulting in high overall assembly cost.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances inview. It is the main object of the present invention to provide anauxiliary clamping operation device for spray can, which simplifies theoverall composition and assembly steps, and saves effort and extendsservice life and quality.

To achieve this and other objects of the present invention, an auxiliaryclamping operation device includes a grip. The grip includes twoclamping parts disposed at one end thereof, and a receiving spacedefined between the two clamping parts. Each clamping part has atriggering portion and a positioning portion disposed on opposite sides.The two trigger portions are fastened together so that the twopositioning portions are drivable by the trigger portions to movebetween an open position where the spray can is separable from theclamping parts, and a close position where the clamping parts clamp thespray can.

Other advantages and features of the present invention will be fullyunderstood by reference to the following specification in conjunctionwith the accompanying drawings, in which like reference signs denotelike components of structure.

DETAILED DESCRIPTION OF THE INVENTION

The technical content and features of the present invention aredescribed hereinafter with reference to the annexed drawings. Thepresent invention can be widely applied to spray cans of various formsor specifications. Those skilled in the art can understand that theexplanatory terms of the present preferred embodiment belong to ageneric description that does not limit the application. For example, amaterial or shape term includes, without limitation, the material orshape specified by the description, and the positional terms include andare not limited to setting, approaching, connecting, or abutting. Thequantity “a” of each component includes the number of one or morecomponents. The directional expressions such as “upper”, “lower”,“inside”, “outside”, “top” and “bottom” mentioned in the contents ofthis specification are merely illustrative terms used in the normaldirection of use, not intended to limit the meaning of the claim.

Referring to FIGS. 1-5, an auxiliary clamping operation device for spraycan in accordance with a first embodiment of the present inventionincludes a grip 10 consisting of two half shells 12. Each half shell 12is made of plastic material, so that each half shell 12 can have a smallamount of deformation. The top of the grip 10 is formed with twoclamping parts 20, and a receiving space 14 is formed between the twoclamping parts 20 for receiving the top of a spray can 30. A dischargeport 16 is defined between the two clamping parts 20 and disposed incommunication with the receiving space 14 such that the discharge port16 corresponds to the valve 32 of the spray can 30. The two clampingparts 20 respectively have a triggering portion 22 and a positioningportion 24 disposed on opposite sides of each other. The two triggerportions 22 are abutted to each other and fixed together by a fasteningmember 26. In this embodiment, the fastening member 26 is a screw. Afterthe two trigger portions 22 are fixed together, the two positioningportions 24 can be driven by the two trigger portions 22 to move betweenan open position (as shown in FIG. 7) or a close position (as shown inFIG. 6). When the positioning portions 24 are in the open position, thespray can 30 can be separated from the clamping parts 20. When thepositioning portions 24 are in the close position, the clamping parts 20can clamp the spray can 30.

The grip 10 further includes a pressing member 40 having an operatingportion 42 and a pressing portion 44. The pressing member 40 is pivotedinside the grip 10. The operating portion 42 extends to the outside ofthe grip 10. Further, the pressing portion 44 is disposed within thereceiving space 14 above the valve 32 of the spray can 30. The user canhook the operating portion 42 while holding the grip 10 and let thepressing portion 44 act upon the valve 32 of the spray can 30.

By using the above-mentioned constituent members, the two clamping parts20 for positioning the spray can 30 can be combined with each other byusing only the fastening member 26, and no additional components arerequired. After the trigger portions 22 are pressed, the positioningportions 24 can be controlled to secure or release the spray can 30stably. The auxiliary clamping operation device is convenient to use,simplifies the overall composition and assembly steps, and saves labor,thereby prolonging the service life and quality of use.

In order to reinforce the structural strength and positioning functionbetween the two clamping portions, the fastening member 26 can befurther provided with a washer and then fixed to affix the two triggerportions 22. Thus, in addition to increasing the bonding strength of thetwo trigger portions 22, the positioning force between the twopositioning portions 24 can be enhanced, and the spray can can besecured more firmly.

Referring to FIGS. 8-10, an auxiliary clamping operation device forspray can in accordance with a second embodiment of the presentinvention is shown. The constituent members of this second embodimentare the same as the first preferred embodiment. The main feature is thatthe fastening member 50 comprises a spring 52 and two pins 54 are placedat each end of the spring 52, the fastening member 50 is providedbetween the trigger portions 22, so that the two trigger portions 22 canalso abut each other and be fixed together, and the two positioningportions 24 can also be driven by the two trigger portions 22 to movebetween an open position (see FIG. 10) or a close position (see FIG. 9).
